Can anyone give some idea what is this PAL lens and the specs?
Patient said they were from a VSP doctor (not too much info there, really!!). The Rx is around -3 or -4. A quick google search does not come up any useful info.
On nasal side: a small circle on top; "VSPVi" at bottom
On Temple side: "G" on top; "22P7" at bottom
great thanks
